To Help My Sister

Hi,my sister is suffering from various symptoms. She has been to a doctor numerous times for blood tests, but has gotten no answers. She is to the point where she can barely function at work, or live a normal life. She spends most of her time in bed. She is suffering from achiness, swelling of the joints, dizziness, headaches, stiff neck, panic attacks, & has had a rash or two,the list goes on. Last week she was feeling so bad, she went to the emergency room, where they took more blood. They keep telling her that nothing is showing up, except a positive result to something called a anti nuclear antibody. My mother-in-law is a nurse & seems to think it could be lymes disease but has never had any hands-on experience w/the disease. I desperately want to help my sister, she lives across the country & has no family w/her to go along to the doctor app.'s. What are the symptoms of lymes disease & what kind of test needs to be ran on her? Any information you can give us would be appreciated!!!
